PATENT FFICEO HARRY ROBERTSON, OF NEYVV YORK, N. Y., ASSIGNOR OF ONEHALF TO v GEORGE W. RAYNER, OF SAME PLACE.

APPARATUS FOR MAKING CARBONATED BEVERAGES.

SPECIFICATION forming part of Letters Patent No. 351,126, dated October 19, 1886.

Application filed Xovember T, 1885. Serial No. 182,118. (No model.)

To all whom it may concern.-

Be it known that I, HARRY RoEERTsoN, of the city and county of New York, in the State of New York, have invented a new and useful Improvement in Apparatus for Making Carbonated Beverages, .(for which I have obtained British Letters Patent N 0. 2,565, dated February 25, 1885,) of which the following is a specification.

My invention relates to that class of apparatus which comprise a pump by which water or other liquid and carbonic-acid gas are taken from separate holders or reservoirs and discharged together into a receiver, from which the carbonated liquid may be taken for bottling or for any other purpose. This receiver usually contains a rotary agitator or stirrer, whereby the liquid and gas within the receiver are subjected to agitation for the purpose of facilitating the mixing of the gas and liquid, or, in other words, for aerating the liquid. Such 'receiver is usually provided with a safety-valve, from which gas escapes and is returned to the gas-holder when the pressure of gas in the receiver is increased to an undesirable degree. In operating such an apparatus the bottler or attendant has, in case he is obliged to leave his machine for any purpose, to first shift the driving-belt or otherwisestop the machine, as the pump, if allowed to continue its operation,would fill the receiver full of liquid, and thereby entail liability of breakage, because thesafety-valve usually employed is not large enough to take away the surplus liquid as fast as delivered by the pump.

An important object of my invention is to provide for automatically regulating the supply ofliquid passing through the pump to the receiver by the amount of liquid in the receiver, so that when the desired liquid level is reached the flow of liquid to the pump will be automatically shut OE and the pump prevented from discharging any more liquid into the receiver.

A further object of the invention is to dispense with the rotary agitator or stirrer ordinarily arranged in the receiver, and to pro vide means whereby the liquid and gas will be thoroughly mixed and incorporated together on their way from the pump tothe receiver.

Patented in England February 2;), 1885, No. 2,565.

The invention consists in novel combinations of parts hereinafter described, and pointed out in the claims, whereby the aforesaid objects are attained.

In the accompanying drawings, Figure 1 is a longitudinal vertical section of an apparatus embodying my invention. Fig. 2 is a horizontal section thereof upon the plane of the dotted line 00 m, Fig. 1; and Fig. 3 is a trans verse vertical section upon the plane of the dotted line y y, Fig. 1.

Similar letters of reference designate corresponding parts in all the figures.

The frame of the apparatus may be of any suitable construction and material. As here represented it consists of two end frames or standards, A A, having at their top bearings a,wherein is supported a crankshaft, B, which may be rotated by hand or by power. I have here shown this crank-shaft as provided with fast and loose pulleys B B to receive a driving-belt, and with a fly-wheel, B to steady itsrotation. Upon one end of the crank-shaft B is a crank, 1), serving to operate tlle pumpplunger 0, which is fitted to a pump-barrel, C. The upper end of the plunger 0 is secured in a cross-head, c, which is fitted to reciprocate vertically in guides c, and which is connected by a rod, 0 with the crank I). The end frames or standards "are connect-ed by cross portions or strct-chers A, and are supported upon a base-plate, A

D designates the receiver for carbonated liquid, which is constructed of brass or other metal, and which is capable of withstanding a heavy internal pressure.

E is a water box or chamber, from which liquid is taken by the pump and delivered mingled with gas into the receiver D. Between the pump and receiver are a number of incorporating-vessels or incorporators, F, through which the liquid and gas are passed, and by which they are mixed or incorporated together as they pass from the pump to the receiver D.

Such being the principal parts of my improved apparatus, I will proceed to describe in detail their construction and manner in which they are combined together.

The pump has at the base of the barrel or chamber 0 a valve-box, 0 containing suitable inlet and outlet passages and valves. The

water-box E is to be supplied with water or other liquid to be carbonated from any suitable source-such as an elevated reservoirthrough a pipe, 6, and the flow of water from 5 this pipe. into said box will preferably be controlled by a float-actuated valve-such as is commonly used in carbonating apparatusand which I have not shown, as it forms no partof my invention. From the water box E the i liquid is taken to the pump by asuction-pipe, 6', wherein is arranged a valve, 6 to which I shall hereinafter refer more particularly, and gas is supplied to the pump through a pipe, f,

from a gas-holder. (Not here shown.) The r receiver D is provided with asafety-valve, f, which may be similar to those ordinarily used in carbouating apparatus. and the overflow from this saftty-valve is delivered by a pipe, f into the main gassupply pipefifrom whence it will again pass to the pump. ,The receiver also has connected with it a pressure-gage,f for indicating the degree of pressure within it. Upon the upstroke of the pump-plunger 0 gas and liquid are drawn in from the pipes e 2 f, and upon the downst-roke of the plunger the gas and liquid are discharged through t-he-discharge-pipe d.

The incorporators F consist of invei-tedcupshaped vessels open at the lower end, and 0 which may be made of glass or metal. Each incorporator-vessel F has a flange at thelower end, and is secured by a gland, g, in the cupshaped or recessed base portion 9. The base portions for the several receivers are construct- 5 ed with tubular passages, which are intercepted by partitions (1*, as best shown in Fig. 1. From the base portions 5/ tubes 9 extend upward into each of the incorporators' F and the passage d, and the tubes 9 are of gradually- 40 decreasing size from the receiving side of the series of incorporators,where the pump is situated, to the delivery side of said series, from whence a pipe, (1, extends to the receiver D. The liquid and gas delivered by the pump 4 5 are discharged from the passage d and upward through the tube g in the first incorporator, and in falling from the top to the bottom of said incorporator the gas and liquid become thoroughly mixed. From the bottom. of the first incorporator the liquid and gas are delivered through the passage d and the tube 9 of the second incorporator, by which they are still further mixed, and so on to the third incorporator, by which their mixing is completed,and the liquid,then thoroughly charged with gas, is delivered through the pipe d to the receiver D.

, It is advantageous to have the passage d and the pipes g of gradually diminishing size throughout the series of incorporators, because then the liquid and gas discharged'from the pump receive a stronger impulse upward through the pipes g as it nears the end of the. series of incorporators, and the effective com: mingling of the two is thereby promoted.

The receiver D, unlike those ordinarily employed in carbonating apparatus, is not fixed in position, and is supported by trunnions or knife-edged pivots h in hangers G, which depend from the frame of the machine. Goncentric with these trunnions are sockets or stuffing-boxes h, which respectively receive the pipe d, whereby the mingled liquid and gas are delivered to the receiver and the pipe H, whereby the gas and liquid are to be drawn from the receiver by the bottler. Inasmuch as these pipes are concentric with the pivots or trunnions of the receiver, they do not inter fere with its swinging in a vertical plane on these pivots or trunnions.

Connected with. the pivots or trunnions h are levers I, which are provided with adj ustable weights 1, and which are designed to balance the weight of the receiver when it is filled with liquid to the level which it is desired to maintain therein. For example, ifit is de sired that the receiver shall be halt full of liquid, the weights 1 are set so that they will just balance the weight of the receiver when filled to that extent, and so that any excess in the receiver beyond that limit will cause the receiver to fall slightly and raise the weights.

The receiver is composed of cast metal, and is provided with an inlet-passage, d'*, with which the pipe d communicates, and an out let-passage, h*, which communicates with the delivery-pipe H. The position of these passages will be readily understood from Fig. 2.

The valve e, which I have before referred to, and which is in the supply'pipe whereby liquid is delivered to the pump, is directly connected with the receiver by a chain, 2', or other suitable connection, so that said valve will be closed and prevent the flowing of liquid to the pump when the receiver, by the increase of liquid within it, overbalances the weights I and falls.

I have here represented stops for limiting the downward movement of the receiver, consisting of rods J, which pass through a crossbar or abutment, A attached to the framing of the machine, and which also pass through lugs or ears 01 uponthe receiver D. Upon these rods are fitted nuts j, which may be ad justed so as to permit any desired degree of swinging movement of the receiver D; and K designates springs applied tothe stop-rods J, and forming a cushion which eases the stopping of the receiver as it falls upon its trunnions h. The arrangement of these parts for balancing the receiver D and for limiting its swinging movement will be best understood from Fig. 3, where they are clearly illustrated.

When the quantity of liquid in the receiver is only equal to or below that desired, the receiver will be maintained in an elevated position by the weights 1, and the valve e will be held open by the chain or connection '5, and will allow a free suction to the pump. In case the receiver falls by reason of excess of liquid within it the chain or connection 11 will become slack and the valve 6 will be closed.

IIIC

It will be seen that I provide for automatically regulating the amount of liquid admitted to the receiver D, so that in case the bottler desires to leave his machine for any purpose there will be no danger of the receiver becoming overcharged with liquid, or the operation of the pump will be allowed to continue, and as soon as the liquid in the receiver reaches the level desired the receiver will fall by its weight and will shut off the supply of liquid to the pump.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a carbonatiug apparatus, the combination, with areceiver mounted to vibrate slightly upward and downward, and a balancing device therefor, of a pump for delivering liquid to the receiver, a suction-pipe leading to the pump, a valve in the suction-pipe, and a connection through which the valve will be closed on the downward movement of the re ceiver, resulting from an excess of liquid therein, and the supply of liquid to the pump be thereby stopped, substantially as herein described.
